Title (EN) MICROCAPSULE AND FILM
(FR) MICROCAPSULE ET FILM
(JA) マイクロカプセル及びフィルム
Abstract:
(EN) The present invention addresses the problem of providing: a microcapsule having excellent quantum yield and durability; and a film containing the microcapsule. The microcapsule according to the present invention contains a core substance and an outer shell layer that covers the core substance, wherein the core substance contains quantum dots and a dispersion medium that has a liquid form at 25°C, the material for the outer shell layer is at least one resin selected from the group consisting of a urea-based resin, a melamine-based resin, a polyurethane-based resin, a polyurea-based resin, a polyamide-based resin and a copolymer resin composed of at least two of these resins, the core substance has a radius of 10 nm to 10 μm inclusive, the outer shell layer has a thickness of 5 nm to 9 μm inclusive, and the ratio of the thickness of the outer shell layer to the radius of the core substance is 0.50 to 0.90 inclusive.
(FR) La présente invention a pour objt de fournir une microcapsule ayant un excellent rendement quantique et une excellente durabilité, et un film contenant la microcapsule. La microcapsule selon la présente invention contient une substance coeur et une couche écorce qui recouvre la substance coeur, la substance coeur contenant des points quantiques et un milieu de dispersion qui se présente sous forme liquide à 25 °C, le matériau de la couche écorce est au moins une résine choisie dans le groupe comprenant une résine à base d'urée, une résine à base de mélamine, une résine à base de polyuréthane, une résine à base de polyurée, une résine à base de polyamide et une résine copolymère composée d'au moins deux de ces résines, la substance coeur a un rayon qui vaut de 10 nm à 10 µm, la couche écorce a une épaisseur qui vaut de 5 nm à 9 µm, et le rapport de l'épaisseur de la couche écorce sur le rayon de la substance coeur vaut de 0,50 à 0,90.
(JA) 本発明は、量子収率及び耐久性に優れたマイクロカプセル、及び、上記マイクロカプセルを含有するフィルムを提供することを目的とする。本発明のマイクロカプセルは、芯物質と上記芯物質を覆う外殻層とを有するマイクロカプセルであって、上記芯物質が量子ドットと25℃において液体である分散媒とを含有し、上記外殻層の材料が、尿素系樹脂、メラミン系樹脂、ポリウレタン系樹脂、ポリウレア系樹脂、ポリアミド系樹脂、及び、これらの2つ以上の共重合樹脂からなる群より選択される少なくとも1種の樹脂であり、上記芯物質の半径が10nm以上10μm以下であり、上記外殻層の厚みが5nm以上9μm以下であり、上記芯物質の半径に対する上記外殻層の厚みの比が0.50以上0.90以下である、マイクロカプセルである。
